Create pull_request_template.md

[goodylili]

Description

The problem:

We are currently lacking a nicely-formatted Pull Request template.

What is needed:

It should include:

a link to the Contributor License Agreement
a reminder to sign the CLA, if the contributor has not already
Fixes: #1234 as a reminder to include the corresponding issue number, if the PR fixes an open issue
a space for a commit message that the author wants to be applied to a squash merge
Suggestions:

We currently don't have a PR template at all. There is some helpful guidance in the GitHub documentation about creating PR templates.
